(...) Here we report the findings of a multicenter in vitro study performed to assess the antimicrobial activity of 400-nm blue light against bacteria in both planktonic and biofilm growth modes. Blue light was tested against a panel of 34 bacterial isolates (clinical and type strains) (...) All planktonic-phase bacteria were susceptible to blue light treatment, with the majority (71%) demonstr...

the reaction of hydrogen peroxide and  pheny -9-acridinecarboxylate in the presence of rhodamin b as a fluorophore leads to the emission of either bright blue light  or bright red light, depending on the structure of fluorescer and reaction conditions. the light emitter responsible for the chemi luminescence (cl) reaction is acridone and that the blue light produced with out the fluorescers is ...

Article history: Received on: 10/11/2016 Accepted on: 11/12/2016 Available online: 27/02/2017 Six fungal species were isolated from Egyptian soil and identified as Aspergillus flavus, Aspergillus niger, Penicillium canescens, Penicillium crustosum, Penicillium sp. and Fusarium sp. and were tested for their decolorization activity of direct blue dye (DB). Aspergillus flavus and Penicillium canes...

We have applied agarose gel electrophoresis (AGE) to single-walled carbon nanotubes (SWNTs) that have been pre-reacted with metallic-selective ionic radicals and then re-suspended with sodium cholate (SC) surfactant to obtain highly purified (up to 98%) semiconducting single-walled carbon nanotubes (s-SWNTs). The proposed combination method exploits the preferential reactivity with the metallic...
